Area Forecast Discussion
National Weather Service Bismarck ND
945 AM CDT Mon May 11 2026

.KEY MESSAGES...

- Critical fire weather conditions today across western through
  most of central ND, including the James River Valley.

- Areas of frost early this morning over much of the James River
  Valley.

- Windy conditions and low humidity values through the rest of
  the upcoming week may lead to daily critical fire weather
  conditions.

&&

.UPDATE...
Issued at 945 AM CDT Mon May 11 2026

A warm front is moving into western North Dakota at the time of
this mid morning update, promote weak radar returns across
portions of the northwest. With very dry conditions underneath
the 10kft cloud bases, it is unlikely that much if any
precpitation associated with these returns are reach the ground.
Have opted to leave very low chances for precpitation (less
than 10 percent) in the forecast at this time. As we head into
the afternoon, cooling and saturated conditions aloft will
promote at least low chance (10 to 30 percent) for rain showers
across portions of the northwest and north central through the
early evening. Otherwise, at this time, winds continue to
organize out of the south southeast with speeds from 15 to 20
MPH and gusts up to 30 MPH already found across the west. Wind
are expected to continue strengthening through the late morning
and afternoon, veering to the northwest as a cold front drops
from northwest to southeast through the evening. Overall, no
major adjustments to the forecast were performed with this
update as it remains in good shape.

UPDATE
Issued at 636 AM CDT Mon May 11 2026

The forecast remains on track.

&&

.DISCUSSION...
Issued at 502 AM CDT Mon May 11 2026

The forecast challenge for the week remains mostly dry and
frequently windy conditions. The overall biggest impacts will be
in regard to fire weather. Those are primarily discussed in the
Fire Weather section below.

Currently, surface high pressure sits over Minnesota and the
western Great Lakes Region, while a surface low is along the
southern Alberta/Saskatchewan border. This low will gradually
slide across the International border through the day today. A
tightening pressure gradient will help produce gusty southerly
winds, especially east of Highway 83 this morning. These winds
are currently forecast from 25 to 35 mph with gusts up to 45
mph. As the low slides eastward, associated cold frontal
boundary will cause winds to switch to a northwesterly
component from west to east across the state this afternoon and
evening. There remains the potential for isolated showers and
thunderstorms late this afternoon and early evening, especially
for northern North Dakota. With inverted V type soundings, any
showers and thunderstorms could produce further enhanced and
erratic wind gusts.

With the exception of the far northwest, the strongest pressure
rises and CAA remain favored for after sunset. In the far
northwest, this could result in very windy conditions this
afternoon similar to those east of Highway 83 in the morning and
early afternoon. However, this unfavorable timing may help limit
peak winds overall. Still, there remains the possibility that
winds are somewhat underforecast for at least a few hours
overnight.

For Tuesday, a strong LLJ is progged to remain in place during
the morning over the eastern half of the state before gradually
moving off further to the east. In addition, surface high
pressure will begin to nudge its way in resulting in a loosening
pressure gradient. Nevertheless, with sunny skies, it should be
a good mixing day. Therefore, do expect there will be windy
conditions yet again, especially in the eastern half of the
state. Still, it remains possible that the NBM 5.0 could be a
little overdone, especially in regard to sustained winds. Either
way, winds should rapidly become light and variable with the
loss of diurnal heating in the evening.

The next surface low will then approach from the lee of the
northern Rockies starting Wednesday, and pass across southern
Canada or North Dakota to finish out the workweek. This will
produce another round of windy conditions, mostly in the west on
Wednesday, then statewide Thursday and possibly Friday
depending on the speed and track of this low. Low precipitation
chances begin to return towards the end of the workweek with 20
to 40 percent shower and possibly thunderstorm chances statewide
Saturday afternoon through Sunday.

Lows should remain above freezing (40s and sometimes 50s)
through the remainder of the week. Highs today are expected to
range from the upper 60s in northeastern North Dakota to the mid
80s west. Following the aforementioned cold frontal boundary,
highs Tuesday will be from the mid 60s to mid 70s. A warming
trend is then progged Wednesday and Thursday with highs
Thursday mostly in the 80s. A slight cooling trend is then
favored this weekend.

&&

.AVIATION /12Z TAFS THROUGH 12Z TUESDAY/...
Issued at 945 AM CDT Mon May 11 2026

Southerly winds will rapidly increase this morning, especially
in the eastern half of North Dakota. However, until then there
are likely pockets of LLWS, mainly in central North Dakota,
where winds remain light and with more of a southeasterly
component. Any LLWS will diminish as winds pick up over the next
couple hours. Otherwise, a cold frontal boundary will pass
through from west to east this afternoon and evening resulting
in a shift to northwesterly winds. There may be a bit of a lull
in wind speed ahead of the frontal passage. However, very windy
conditions are expected behind the front, especially in
northwestern North Dakota this afternoon and evening. Isolated
showers, along with a few thunderstorms, are possible mainly
during the afternoon and early evening hours. Confidence in
where they develop and at what particular time remains low.
Enhanced and erratic winds are possible with any showers or
thunderstorms that develop. Other than during any potential
precipitation, VFR ceilings and visibility are expected through
the period.

&&

.FIRE WEATHER...
Issued at 502 AM CDT Mon May 11 2026

Surface low moving from west to east across south central Canada
will tighten the pressure gradient and produce increasingly
strong southerly winds this morning. These winds will be
strongest for locations east of Highway 83 that are also along
and south of Highway 2. In addition to strong southerly winds,
marginally higher dewpoints in the 30s to low 40s will advect
into much of the state this morning and early afternoon. An
associated cold frontal boundary will then pass from west to
east across the state this afternoon and evening, which will
quickly lessen dewpoints yet again. When all is said and done,
there will be a sharp gradient in minimum relative humidity
this afternoon with much drier conditions west versus east. In
addition to relatively brief increased dewpoints, there will
likely be somewhat of a lull in winds ahead of the frontal
boundary, followed by a strengthening behind it. This will
produce gusty northwesterly winds across western North Dakota in
the afternoon, especially in the far northwest. The strongest
winds during both time periods and geographical locations will
be from around 25 to 35 mph with gusts up to 45 mph.

Strong winds combined with these low humidity values will
result in critical fire weather conditions today for most of
western through central North Dakota, including the James River
Valley. Of note, one additional concern for this afternoon and
early evening is the potential for isolated showers and a few
thunderstorms. While any precipitation is not expected to be
widespread, inverted V soundings suggest enhanced erratic winds
are possible with any shower or thunderstorm activity that does
occur.

Winds will become light across most of the western half of the
state tonight, though remain breezy to windy in the eastern
half. That said, higher pressure rises and strong CAA could
maintain a bit stronger winds than currently forecast. At least
for a few more hours. Another windy day is then expected
Tuesday with strong northwesterly winds, especially east of
Highway 83 where winds may once again range from around 25 to 35
mph with gusts up to 45 mph. Locations further west should
remain moderately lighter, albeit still breezy at around 15 to
20 mph. The one thing that does lower confidence in winds
reaching their maximum potential on Tuesday is a loosening
pressure gradient, and a strong LLJ that may move off to the
east by the afternoon. Still, a good mixing day favors windy
conditions that when combined with continued dry conditions,
will likely be enough to result in critical fire weather
conditions once again for much of central North Dakota, and
possibly western North Dakota as well.

Beyond Tuesday, low minimum relative humidity values will occur
daily through the remainder of the workweek. Meanwhile, breezy
to windy conditions are expected again Wednesday afternoon,
especially in the west, while windy conditions are favored
across most of the state Thursday. Things become more uncertain
towards the weekend, though precipitation chances do increase
with widespread 20 to 40 percent chances currently in the
forecast Saturday night through Sunday.
